I have a home-made DM screen stuffed into my bookshelf. It is only remarkable because I also made it out of black foam core and black tape. The 'necessary charts' are printed out on paper and taped inside.I never got around to decorating the outside of it.My other favorite screen is an old "D&D" one that has skulls drawn on paper and pasted to the front of the screen (a skull representing a PC death). Unfortunately, I didn't keep up on my kills so the screen is out of date, but hopefully it would inspire fear in the players.
